for those of you with aftermarket boost guage questions, at idle or off throttle, do you have any reading at all or does it hang around 0?

at idle you should have between 15 and 20 inches of vac.

that must mean i have a vac leak because im only reading boost and no vac whatsoever. BTW i have a blitz boost guage,

it also runs fine besides my 3800 problem and my car running very excessivley rich (which i cant figure out).

You're using the wrong fitting.
You're currently using a fitting that is before the TB - you need one AFTER the TB.

I have a posisitve pressure only guage. Should it still be after the TB or will it matter?

I'll probably T into the boost sensor line.

I'm just wondering. I would assume that on release of the pedal on an open atmo BOV you might see a small/short spike if placed before the TB.

You are correct - it doesn't matter in this case.

is there already a spot after the TB that i can tap into?

Anything after the TB.
You can "T" into the boost sensor or BOV line on the passenger side - this is probably easiest for you.
